Application filed January 14, 1914. Serial No. 812,105.

To all whom it may concern:

Be it known that we, CLARENCE A. FUL- LEnToN, LEROY A. RUsHwoRTH, and VV1L- LIAM H. PAETH, citizens of the United States, and residents of New. York, county of New York, and State of New York, and Providence, county of Providence, and State of Rhode Island, respectively, have invented certain new and useful Improvements in Metallic Framing, and do hereby. declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallic construction for doors, frames, tubular and open metal sections wherein it may be necessary to connect two or more metallic sections transversely and more or less continuously through their lengths, and the like and has for an object to provide an improved means for forming the frames of interlocked metal.

A. further object is to provide means for forming tubular sections which are subsequently formed into doors or the like.

Further objects will be apparent from the following specification, appended claims and drawings in which,

Figure 1 is a side elevation of a door constructed in accordance with this invention. Fig. 2,is a cross sectional view as on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view as on the line 4'4. of Fig. 1. Fig. 4 is a cross sectional view looking upwardly showing how the door is mounted when used for a double swinging door. Fig. 5 is a cross sectional view showing how the hinge is applied to one of the stiles, Fig. 6 is a cross sectional view through a modified form, and Figs. 7 and 8 are cross sectional views of modified forms.

This invention'provides for the construction of bronze doors and thelike. It provides a simplified means of forming the frame work of the door in permitting the interlocking of sections of drawn or otherwise formed lengths of metal. This frame work when'made up possesses the necessary strength for such usage and also presents a comparatively light structure.

In carrying out this invention, the'stiles and head rail of a door, a railing or any other similar structure are formed of two lengths of metal which may be drawn or otherwise formed in the desired shape, and these lengths of metal are assembled by sliding one section longitudinally over or within the other.

Referring to the drawings in which similar reference numerals indicate similar parts throughout the several views there is shown a door A which has the stiles and head rail thereof formed of U shaped channels 10 to which applied a cap section 11. The-metal comprising the channel sections l0 and caps 11 may be worked through dies, cast or machined and may be of any desired cross sectional configuration. In the drawings the channel sections 10 have portions 12 of increased width, and stepped portions 13 which terminate in the constricted side flanges 14. These flanges are provided at desired points with beads 15 and with dovetailed flanges 16 between the beads 15 and the edges of the flanges 14, to form dovetailed recesses 17 to receive corresponding beads 18 carried by the flanges 19 of the cap pieces 11. The cap pieces 11 may have portions thereof depressed as at f 20 to form shoulders '21, or these cap pieces may have flanges 22" formed on the inner side thereof as shown in Fig. 8 or as shown in Fig. 4, they may have a portion of the metal constituting said cap of increased thickness as shown at 23 to form shoulders to arrest the inward movement of the flanges 14. It is apparent that this form of locking means presents a rigid construction in which the flanges 14: are subsequently trussed. When this construction 1s used for bronze doors and the like, the frame of the door is formed of this metal and any desired panel may be inserted in this frame. As shown in the drawings the panel may be of plate glass or any other desired material and this panel 24 is retained by fillets 25 and 26 of which, the fillet 25 is secured by passing screws through the portions 12 into the under side of the fillet 25 while the fillet 26 may be removed when it is desired to instiles and head rail are mitered as at 27 and the base is fitted by mitering the stiles as at 28 having the flanges 14 abut against the shoulder 29 formed on the side plating 32.

When the door is to be swung on strap hinges, as shown in Fig. 5 of the drawings a portionof the cap l1 is removed to admit the leafof the hinge into the recessed portion of the cap as shown. The leaf may then be fastened to the door in the usual manner and to the stile of the door casing'as in common practice.

As doors or the like made in accordance with this invention will be required for use in various places and under various conditions, different cross sectional outlines will be required for the diflerent uses. Fig. 6, shows one of the many possible modifications whielrcanbelnade.

Figs. 7 and 8 show modifications-wherein more. than -two piecesof material are secured by the construction-disclosed in this invention. a a

It is apparent from the foregoing and the drawings that the parts. 10 and 11 must be assembled by sliding one portion into or over the others by a longitudinal movement and that when the parts are so assembled they are positively interlocked to reinforce the intermediate sections.

' 'Having thus described our invention, we

interlocked channel structures having complemental flanges, the flanges of one section extending between the flanges of the other section, some of said flanges having spaced beads being undercut to present a dovetail one of said channel members to engage the ends of the inserted flanges to reinforce the same.

3. In a construction of the class described, channel structures having complemental flanges therein, the flanges of one member extending between those of the other member, said flanges being of difl erent widths to'cause the flanges of one section to terminate at points within the width of the other flanges, one of said channel structures having projections formed on the base thereof, to engage the ends of the wider flanges, spaced beads formed on said wider flanges, said beads comprising an undercut slot, and inwardly directed undercut beads formed on the inner faces of the smaller flanges to engage in said undercut slot of the larger flanges, said arrangement comprising a structure in which the flanges are reinforced in having the larger flanges supporting on the opposite edges thereof.

In testimony whereof we aflix our slgnatures 1n presence of witnesses.
